myUserList AppUsers = new myUserList();
using (PrincipalContext pcxt = new PrincipalContext(ContextType.Domain, domainName))
{
UserPrincipal User = new UserPrincipal(pcxt);
User.EmailAddress = emailString;
PrincipalSearcher srch = new PrincipalSearcher(User);
foreach (var principal in srch.FindAll())
{
var p = (UserPrincipal)principal;
myUserRow User = AppUsers.NewUsersRow();
User.FirstName = p.GivenName;
User.LastName = p.Surname;
User.Email = p.EmailAddress;
AppUsers.AddUsersRow(User);
}
}
I have code similar to the above that searches Active Directory for user information using PrincipalContext class.
As you can see i pass in the domainName during the search. How can i modify this peace of code to instead search the entire forest (i.e Global Catalog) but still use the PrincipalContext class?
I can't seem to find a working example that uses PrincipalContext class to do a Global Catalog search.
I have seen this post How to search for users in Global Catalog within AD forest with multiple trees but the poster seems to suggest that they did not find a solution that uses PrincipalContext class, they had to switch back to DirectorySearcher.
Is there any PrincipalContext class code sample that demonstrates searching in the whole forest (Global Catalog)?
回答1:
ok, i got it working. I just had to change my code like below.
myUserList AppUsers = new myUserList();
using (PrincipalContext pcxt = new PrincipalContext(ContextType.Domain, "my-global-catalogue-server.subdomain.domain.com:port", "DC=subdomain,DC=domain,DC=com"))
{
UserPrincipal User = new UserPrincipal(pcxt);
User.EmailAddress = emailString;
PrincipalSearcher srch = new PrincipalSearcher(User);
foreach (var principal in srch.FindAll())
{
var p = (UserPrincipal)principal;
myUserRow User = AppUsers.NewUsersRow();
User.FirstName = p.GivenName;
User.LastName = p.Surname;
User.Email = p.EmailAddress;
AppUsers.AddUsersRow(User);
}
}
